14 ALASKAN GLACIER STUDIES the ice tongues of Prince William Sound, Tazlina Glacier perhaps connecting with Columbia Glacier, Matanuska Glacier with Harvard and Yale Glaciers, and Knik Glacier with Barry or some other glacier of Harriman Fiord. Just north of the Chugach Mountains are the Talkeetna Mountains, 5000 to 750G feet high, within which are a series of smaller glaciers, the Chickaloon, Talkeetna, and others, observed by soldiers accompanying Captain, Glenn,1 by Martin,2 and by Paige and Knopf, and shown on the same maps as those of the northern Chugach. Glaciers of the Kenai Peninsula. The Kenai Mountains, which continue the Chugach Mountains to the southwest and form the west end of the St. Elias Range, rise to heights of 6000 to 7000 feet and send valley glaciers east to Prince William Sound, south to the Gulf of Alaska, and west toward Cook Inlet. There are many tidewater glaciers in western Prince William Sound and on the south of the Kenai Mountains, but none that discharge directly into Cook Inlet on the west. The ice tongues of western' Prince William Sound include the Portage Glacier, the glaciers of Blackstone Bay, Port Nejlie Juan, and Icy Bay. There are glaciers on the south side of Kenai Peninsula in Port Bainbridge, Fairneld and Days Harbors, Resurrection Bay, AiaJik and Nuka Bays, and Port Dick. In the interior of the peninsula small glaciers discharge into Glacier River,8 into the stream feeding Lake Skilak, and into Lake Tustumena. In the southwestern part of the peninsula the Grewingk, Wosnessenski, Doroshin, and Southern Glaciers descend nearly to Kache-mak Bay and Cook Inlet. Several of these are through glaciers, as the Portage Glacier of Passage Canal and Turnagain Arm, the Southern Glacier of Tutka Bay and Port Dick, etc. A number of the glaciers of the south coast of Kenai Peninsula were discovered by the Russians and are shown on Tebenkof's chart of 1849. Those in western Prince William Som/d were mapped by Vancouver's lieutenant, Whidbey, in 1794 4 and by Applegate in 1887.6 The glaciers of Kachemak Bay were visited by Dall in 1880, by Dall,8 Becker and Curtiss7 in 1895, and by Gilbert and the Harriman Expedition in 1899.8 Grewingk Glacier retreated about 250 feet between 1880 and 1895, and 350 feet between 1895 and 1899. Dall and Beckerfl have alluded to the evidences of former glaciation in Kodiak and Wood Islands, the westward extension of the Kenai Mountains, as amplified later by Gilbert.10 No glaciers are known on Kodiak Island. 1 Hattys, F. and Bagg, J, S., Compilation of Narratives of Exploration in Alaska, Washington, 1900, pp. 681, 682-683. • Martin, G.
